The AXG aluminum grip module provides a solid, metal-frame feel with a flared magwell and replaceable textured G10 panels. At 36.1 oz, it offers stable handling while maintaining the compact form factor and 17+1 capacity.
The stainless slide wears Legion Gray Cerakote Elite and features front and rear serrations, Legion chevron engraving, an optics cut, two rectangular top ports, and a slide-integrated expansion chamber. Sig literature notes the integrated expansion chamber can reduce recoil by up to approximately 25%.
X-RAY3 day/night sights pair a high-visibility green-ring tritium front with tritium rear dots. The front sight includes a sight-height number for easy reference.
The striker-fired system uses a flat, skeletonized trigger and a push-button magazine release. A full-length M1913 accessory rail is machined into the frame. This configuration does not include a manual safety.
Key dimensions include a 3.9 in barrel, 8.2 in overall length, 5.5 in height, and 1.6 in width. The pistol is marked "SIG SAUER INC., NEWINGTON NH USA," with the serial visible on the FCU window, and comes with two 17-round magazines.
